This project aims to detect the tiny twisting forces imparted by a single quantum spin on a host diamond nanocrystal levitating in vacuum. Our team will build both a hypersensitive detector of quantum rotations and the complex theoretical models for quantum spin systems coupled to the mechanical motion of nanometre-sized diamonds. The expected experimental capabilities and knowledge generated by this project will enable world-first measurements of quantum effects with unparalleled sensitivity and powerful new quantum sensing paradigms. The project should enable significant benefits, such as incisive tests of the limits of quantum theory and new Australian technology operating at the interface of the quantum and classical worlds.

该项目旨在检测通过真空中的宿主钻石纳米晶体悬浮在真空中的宿主钻石纳米晶体上赋予的微小扭曲力。我们的团队将建立量子旋转的高度检测器，也将建立与纳米尺寸钻石的机械运动相连的量子自旋系统的复杂理论模型。该项目产生的预期实验能力和知识将以无与伦比的灵敏度和强大的新量子传感范式来实现世界优先的量子效应。该项目应带来重大的好处，例如对量子理论限制和在量子和古典世界界面运行的新澳大利亚技术的尖锐测试。
